| Outline of Final Research Achievements |
In these days, large scale earthquake is frequency occurred in the world, and damages are caused by the earthquake. Therefore, it is necessary to take effective measures for prevent the earthquake damage. To reduce the earthquake damage, we have devised a magnetic levitation type superconducting seismic isolation device which composed by the HTS bulks and permanent magnets. In order to realize this device, we must improve the magnetic levitation force that contributes to the magnetic coupling between the HTS bulk and PM rail. However, the vertical vibration transmission to the seismic isolation object is increased with magnetic coupling between the HTS bulk and PM rail. Therefore, it is closely related to the magnetic levitation force improvement and vertical vibration transmission. We made an attempt at append a coil with superconducting wire to the HTS bulk. As a result, the magnetic levitation force slightly decreased, but it is succeed to reduce the vertical vibration transmission.
